adjustment slot and turn it counter-clockwise to increase or clockwise to
decrease by-pass flow. At the completion of the brewing cycle, measure
the volume of the water in the coffee liner. The timer may have to be
readjusted to obtain the correct volume of water. The proper setting of
the by-pass will have to be determined by the user.
THERMOSTAT: To adjust the temperature of the water in the urn, turn
the thermostat knob to “10”and remove the knob without moving the
thermostat shaft. Place narrow bladed screwdriver (1/8”) into the hollow
thermostat shaft and engage center adjustment screw. When
thermometer reading approaches 198F slowly turn the adjustment screw
clockwise until the burner goes out. Turning the screw counter-clockwise
will increase the temperature.
MAINTENANCE TIPS
WATER CONDITION: Remove and clean spray head cap and spray head
disc frequently-typically once a week. To clean the swivel valve, loosen
nut and remove spray arm assembly from urn. Sediment may be
removed by inserting a pipe cleaner through small hole in valve. If
maximum setting of timer fails to deliver enough water, check water
pump.
OUTSIDE SERVICE: Should you require help, contact the factory, your
factory representative, or your local service company.
FOR QUALIFIED SERVICE PERSONNEL ONLY
When servicing of unit is required, contact a qualified service agency.
CAUTION: DO NOT TURN ON THERMOSTAT BEFORE ALL PRIMING
